New submission from Terrence Cole <terrence at zettabytestorage.com>:
__annotations__ should be included in the set of attributes copied by default to a wrapped method.
An example of the problem:
>>> from functools import wraps
>>> def mydecorator(fn):
... @wraps(fn)
... def inner(*args, **kwargs):
... return fn(*args, **kwargs)
... return inner
...
>>> @mydecorator
... def foo(a:int, b:str):
... pass
...
>>> foo.__annotations__
{}
With the included fix:
>>> foo.__annotations__
{'a': <class 'int'>, 'b': <class 'str'>}
